Surgical masks, i.e. medical surgical masks, are different from ordinary masks in terms of material and usage. 1. Material: general medical surgical masks are mainly made of meltblown fabrics and nonwoven materials, most of which are divided into three layers and have a filtration layer. The material of ordinary masks can not be determined, there are cotton masks, non-woven masks, activated carbon masks, etc., there is no filtration layer, so the two materials are different. 2. Use: Medical surgical masks are mainly used for medical personnel to wear during surgical operations, which can block and filter viruses, bacteria, droplets, etc. contained in the air entering the nose and mouth. And ordinary masks can only be used for daily protection, can block the dust, no blocking the role of the virus. There is a big difference between medical surgical masks and ordinary masks, and you should choose masks according to your needs in daily life.
